Direct torque
This value is representative of resistance to unscrewing after ageing.

Indirect torque
In most cases, indirect torque resistance is higher (even much higher) than recommended maximum tightening torque for grade 8 nuts with a friction coefficient of 0.20.
The value shown in the data sheets has therefore been limited to the recommended maximum tightening torque for grade 8 nuts with a friction coefficient of 0.20.
In other cases, the value shown in the data sheets corresponds to the recommended torque value that is compatible with STUDFIX™ indirect torque resistance.

This value represents component resistance before assembly.
The push-out force values are provided in the STUDFIX™ data sheets.

Data related to those tests is provided as a guideline only. These values may vary in accordance with the materials used and implementation conditions. It is recommended that tests be conducted in the actual application conditions.
